Kallonlahti 2 – Additional capacity for harbour use
On the Kallonlahti quay site at Mäntyluoto a retaining wall quay was constructed from elements made using the slipform casting technique and installed in position with a floating crane.
-At this site, we once again got the opportunity to utilise Terramare’s core expertise, such as dredging, underwater drilling and blasting, slipform casting and quay construction, says Construction Manager Juha Seppälä.
New environmentally friendly quay at Tahkoluoto
The new retaining wall quay at Tahkoluoto, implemented using the slipform casting technique, is safer for the environment than the chemical harbour’s previous 60-year-old caisson-type oil quay. The structure of the new quay enables the implementation of an efficient and safe unloading and loading system that meets strict standards.
-The fact that the old quay was in use at the harbour and the new quay was being built at the same time behind the old quay presented its own challenges to this site. Smooth communication between the port and the Terramare team was paramount in ensuring safe working conditions, emphasises Seppälä.
Deeper harbour basins – Larger vessels
The harbour deepening dredging included in the contract was handled by Terramare’s diverse and efficient dredging equipment.
The harbour’s new quays enable larger container and ro-ro vessels to moor at the quays, where the navigation depth is 12 metres instead of the previous 10 metres.
The deepening of the fairway by 1.5-2 metres doubles the ship transportation capacity, which in turn brings to shipowners significant savings in port dues.
As a result of the port’s upgrade, it is a modern, competitive and environmentally friendly operator.
